I can't use the provide title feature in rails

Question

I'm trying to use the <% provide (:title, 'home') %> but a syntax error is returned. should I install a gem for it to work. Thanks in advance

I think you're misusing the provide method. What do you want to achieve here? — lcguida

Get rid of the brackets or get rid of the space between provide and first bracket. — BroiSatse

I've seen the use of the provide method in the Michael Hartl tutorial to attain a uniform title — Vic Turuthi

@lcguida - It is common to use provide for page title like this. — BroiSatse

In Ruby the parens around a method call are optional:

provide :title, 'home'

But when using parens there should not be space between the method name and the parens:

def add(args*) args.sum end add 1, 2 # => 3 add(1,2) # => 3 add (1,2) # syntax error, unexpected ',', expecting ')' add (1+2), (1+2) # => 6

In the last examples you can see that Ruby treats the parens as a single argument when there is a space - which is why it gives a syntax error.
